RESUMEN
BACKGROUND AND AIM: Flexible sigmoidoscopy (FS) without analgesia or sedation can be unpleasant for patients, resulting in unsatisfactory examinations. Prior familiarization videos (FVs) and intra-procedural Entonox inhalation have shown inconsistent effects. This study investigated their effects on undesirable participant factors (anxiety, stress, discomfort, pain, satisfaction, later unpleasant recall of procedure, and vasovagal reactions) and clinical effectiveness (extent of bowel seen, lesions detected, and procedural/recovery times). METHODS: This cluster-randomized single-center study evaluated 138 participants undergoing FS. There were 46 controls, 49 given access to FV, and 43 access to both FV and self-administered Entonox. Participant factors were measured by self-administered questionnaires, independent nurse assessments, and heart rate variability (HRV) metrics. RESULTS: Questionnaires showed that the FV group was slightly more tense and upset before FS, but knowledge of Entonox availability reduced anxiety. Nonlinear HRV metrics confirmed reduced intra-procedural stress response in the FV/Entonox group compared with controls and FV alone (P < 0.05). Entonox availability allowed more bowel to be examined (P < 0.001) but increased procedure time (P < 0.05), while FV alone had no effect. FV/Entonox participants reported 1 month after FS less discomfort during the procedure. Other comparisons showed no significant differences between treatment groups, although one HRV metric showed some potential to predict vasovagal reactions. CONCLUSIONS: Entonox availability significantly improved clinical effectiveness and caused a slight reduction in undesirable participant factors. The FV alone did not reduce undesirable participant factors or improve clinical effectiveness. Nonlinear HRV metrics recorded effects in agreement with stress reduction and may be useful for prediction of vasovagal events in future studies.

BACKGROUND: Although young-age-of-onset colorectal cancer is increasing in incidence, lack of screening leads to symptomatic presentation, often with rectal bleeding. Because most cancers in patients younger than 50 years are left-sided, flexible sigmoidoscopy is a reasonable way of investigating bleeding in these patients. OBJECTIVE: To predict which patients undergoing flexible sigmoidoscopy for outlet-type rectal bleeding need a full colonoscopy. DESIGN: Findings at colonoscopy were compared with published indications for colonoscopy after flexible sigmoidoscopy, which were as follows: 1) any number of advanced adenomas defined as a tubular adenoma of >9 mm diameter, a tubulovillous or villous adenoma of any size, or any adenoma with high-grade dysplasia; 2) 3 or more tubular adenomas of any size or histology; 3) any sessile serrated lesion; and 4) 20 or more hyperplastic polyps. SETTING: Charity Hospital with volunteer specialists. PATIENTS: Patients were included if they were younger than 57 years, had outlet-type rectal bleeding, and underwent flexible sigmoidoscopy at least to the descending colon followed by colonoscopy with biopsy of all resected lesions. INTERVENTIONS: Flexible sigmoidoscopy and colonoscopy with excision of all removable lesions. MAIN OUTCOME MEASURES: Findings at colonoscopy. RESULTS: There were 66 patients who had a colonoscopy between 5 and 811 days after sigmoidoscopy and also had complete data. There were 43 men and 23 women with a mean age of 39.5 years. Analysis of flexible sigmoidoscopy criteria for finding proximal high-risk lesions on colonoscopy showed a sensitivity of 76.9%, a specificity of 67.9%, a positive predictive value of 37%, a negative predictive value of 92.3%, and an accuracy of 69.7%. LIMITATIONS: A large number of exclusions for inadequate colonoscopy or inadequate data resulted in a reduced patient number in the study. CONCLUSIONS: Our criteria for follow-up colonoscopy based on the findings at initial flexible sigmoidoscopy in young patients with outlet-type rectal bleeding are reliable enough to be used in routine clinical practice, provided this is audited.

GUA DE EVALUACIN PARA LA NECESIDAD DE COLONOSCOPIA DESPUS DE UNA SIGMOIDOSCOPIA FLEXIBLE INICIAL EN PACIENTES JVENES CON RECTORRAGIA: ANTECEDENTES:Si bien la edad de aparición temprana del cáncer colorrectal está aumentando en incidencia, la falta de pruebas de detección conduce a una presentación sintomática, a menudo con sangrado rectal. Debido a que la mayoría de los cánceres en pacientes menores de 50 años son del lado izquierdo, la sigmoidoscopia flexible es una forma razonable de investigar el sangrado en estos pacientes.OBJETIVO:Predecir qué pacientes sometidos a sigmoidoscopia flexible por rectorragia necesitan una colonoscopia completa.DISEÑO:Los resultados de la colonoscopia se compararon con las indicaciones publicadas para la colonoscopia después de una sigmoidoscopia flexible. Estos fueron: 1. Cualquier número de adenomas avanzados, definidos como un adenoma tubular > 9 mm, un adenoma tubulovelloso o velloso de cualquier tamaño, o cualquier adenoma con displasia de alto grado. 2. Tres o más adenomas tubulares de cualquier tamaño o histología. 3. Cualquier lesión serrada sésil. 4. Veinte o más pólipos hiperplásicos.ENTORNO CLINICO:Hospital de Caridad con especialistas voluntarios.PACIENTES:Menores de 57 años, con rectorragia, sometidos a sigmoidoscopia flexible al menos hasta el colon descendente, seguida de colonoscopia con biopsia de todas las lesiones resecadas.INTERVENCIONES:sigmoidoscopia flexible y colonoscopia con escisión de todas las lesiones removibles.PRINCIPALES MEDIDAS DE VALORACIÓN:Hallazgos en la colonoscopia.RESULTADOS:66 casos a los que se les realizó una colonoscopia entre 5 y 811 días después de la sigmoidoscopia, que también tenían datos completos. 43 hombres y 23 mujeres con una edad media de 39,5 años. El análisis de los criterios de sigmoidoscopia flexible para encontrar lesiones proximales de alto riesgo en la colonoscopia mostró una sensibilidad del 76,9 %, una especificidad del 67,9 %, un valor predictivo positivo del 37 %, un valor predictivo negativo del 92,3 % y una precisión del 69,7 %.LIMITACIONES:Gran número de exclusiones por colonoscopia inadecuada o datos inadecuados que causan un número reducido de pacientes en el estudio.CONCLUSIÓN:Nuestros criterios para la colonoscopia de seguimiento basados en los hallazgos de la sigmoidoscopia flexible inicial en pacientes jóvenes con rectorragia son lo suficientemente confiables para ser utilizados en la práctica clínica habitual, siempre que se audite.

Positive screening tests require investigation, usually by specialists. Specialist services are known to be limited. The planning of screening programmes must first include a model of existing diagnostic and follow-up services of symptomatic patients so that the added impact of the extra referrals required for screening can be estimated. This is fundamental to the planning of screening programmes; inevitable diagnostic delay, impeded access to services for symptomatic patients, and resulting harm or increased mortality from disease can thus be avoided.

AIM: To update activities of the Canterbury Charity Hospital (CCH) and its Trust over the eight-year period 2013 to end of 2020, following previous reports in 2010 and 2013. METHOD: CCH continued to provide free secondary elective healthcare services to some patients in the Canterbury Distinct Health Board (CDHB) region who were unable to access healthcare they needed through public hospitals and were unable to pay for private care. CCH's services were supplied by a large volunteer workforce, supported by a skeleton staff, and were financed solely by charitable giving. Changes occurred periodically in the quantity and nature of regional unmet healthcare need, largely due to changes in services provided by the CDHB. In order to accommodate these changes, major structural and infrastructural developments were necessitated at CCH. RESULTS: Many healthcare services at CCH remained the same as before this period but new changes occurred there as a result of: (i) establishment of a flexible sigmoidoscopy day clinic for the management of fresh rectal bleeding in those under 50 years of age; (ii) requirement for a sudden increase in counselling services immediately after the terror attacks at Christchurch mosques; (iii) expansion of the Dental and Oral Surgery Service; and (iv) interruption of CCH service provision by the COVID-19 pandemic. CONCLUSIONS: CCH continued to fill some of the regional unmet elective healthcare need. This is, however, a national problem as attested by the presence of a charity hospital in Auckland and another being planned for Invercargill. Hopefully present and future governments will appreciate that free universal access to secondary elective healthcare is not only a humane imperative, but also a sound economic investment.

We examined the documentation underlying the decision to permit the Southern District Health Board (SDHB) to join the National Bowel Screening Programme (NBSP) at a time when it was not providing an adequate colonoscopy service for symptomatic patients. A coordinated sequence of relevant Official Information Act 1982 (OIA) requests was lodged with the New Zealand Ministry of Health (MoH), which is responsible for determining the readiness of district health boards (DHBs) to join the NBSP. However, the MoH OIA process was obfuscating, unduly long and responded only after they anticipated imminent intervention by the Office of the Ombudsman. The amount of information provided was massive, partly irrelevant and presented in an inconvenient format. It revealed that the MoH readiness process was incomplete, and permission for the SDHB to join the NBSP was given prematurely without following due process and despite concerns expressed by some MoH staff. Subsequently, the MoH has failed to admit that they made errors in this case or have any weaknesses in their readiness assessment process. The MoH readiness process failed to determine that the SDHB was not ready to join the NBSP in 2018. Concerns have been expressed in the public media that such failures have occurred with the assessment of other DHBs. The process needs to be overhauled or replaced before further permissions are granted to DHBs. Requests for information under the OIA from the MoH, and similar public entities and agencies subject to the OIA, are too easily deferred, derailed or declined. The OIA is in need of revision.

Radical market-oriented health reforms in New Zealand in the early 1990s failed to deliver key financial targets, resulted in unnecessary patient deaths, adversely affected public healthcare services, induced serious tensions between clinicians and managers and encouraged a predisposition to private healthcare. A more co-operative health system was implemented in the late 1990s but remaining problems of inadequate patient access led to establishment of a charity hospital in Christchurch which, by November 2018, had registered over 18 000 patient visits. This is one indication of the need to resurrect our public healthcare system. In this paper, we discuss briefly the health reforms of the 1990s then, for discussion and debate, provide seven suggestions for how this resurrection might be achieved thereby avoiding the need for charity hospitals throughout the country.

Since the 1970s, neoliberalism has been the dominant economic and political philosophy among global institutions and some Western governments. Its three main strategies are: privatisation and competitive markets; reduced public expenditure on social services and infrastructure; and deregulation to enhance economic activity and ensure freedom of 'choice'. Generally, these measures have negatively affected the health and wellbeing of communities. In New Zealand, privatisation and competition led to income inequality and an unequal distribution of the 'determinants of health', a burden borne disproportionately by children, the poor, and by Maori and Pacific people. Limiting health expenditure led to inequalities in access to services with restructuring in the 1990s, subverting the service culture of the health system. Failure to regulate for the protection of citizens has undermined health and safety systems, the security of work and collective approaches to health improvement. There has been some retreat from neoliberalism in New Zealand, but we can do more to focus on 'upstream' health initiatives, to recognise that social investment, including adequate funding of services, returns benefits far in excess of any costs, and to make sure that social and cultural equity goals are achieved.

BACKGROUND: This study reports the quality-of-life assessment of the ALCCaS trial. The ALCCaS trial compared laparoscopic and open resection for colon cancer. It reported equivalence of survival at 5 years. Quality of life was measured as a secondary outcome. OBJECTIVE: This study aimed to report on the quality of life data of the ALCCaS Trial. DESIGN: This study reports a randomized controlled trial comparing laparoscopic with open colonic resection. SETTINGS: The study was conducted in Australasia. PATIENTS: Patients with a single adenocarcinoma of the right, left, or sigmoid colon, presenting for elective treatment, were eligible for randomization. INTERVENTIONS: Open and laparoscopic colonic resections were performed. MAIN OUTCOME MEASURES: Patient symptoms and quality of life were measured using the Symptoms Distress Scale, the Quality of Life Index, and the Global Quality of Life Score preoperatively, and at 2 days, 2 weeks, and 2 months postoperatively. RESULTS: Of the 592 patients enrolled in ALCCaS, 425 completed at least 1 quality-of-life measure at 4 time points (71.8% of cohort). Those who received the laparoscopic intervention had better quality of life postoperatively in terms of the Symptoms Distress Scale (p < 0.01), Quality of Life Index (p < 0.01), and Global Quality of Life (p < 0.01). In intention-to-treat analyses, those assigned to laparoscopic surgery had a better quality of life postoperatively in terms of the Symptoms Distress Scale (p < 0.01) and Quality of Life Index (p < 0.01), whereas Global Quality of Life was not significant (p = 0.056). The subscales better for laparoscopic resection at all 3 postoperative time points were appetite, insomnia, pain, fatigue, bowel, daily living, and health (p < 0.05). LIMITATIONS: The primary limitation was the different response rates for the 3 quality-of-life measures. CONCLUSIONS: There was a short-term gain in quality of life maintained at 2 months postsurgery for those who received laparoscopic relative to open colonic resection.

Physician advocacy occurs when doctors speak up for the health and healthcare of patients and communities. Historically, this was strong in some Western countries with doctors finding that it enhanced their authority, prestige and power. But it weakened in the 20th century when the biomedical model of heath triumphed and medicine became a dominant profession. In the second part of the 20th century, this dominance was threatened by political, technological and socioeconomic forces. These weakened medicine's state support, brought it under managerial control and undermined the social contract on which trust between doctors and the community was based. Defence of the profession was assumed by medical colleges, societies and associations. They had some success in retaining professional autonomy but did not undertake open advocacy, particularly on social justice issues, and did not therefore enhance their standing in the community. Opinion is divided on the level of advocacy that it is ethically proper for the medical profession to employ. Some contend doctors should only advise authorities when expert opinion is requested. Others contend doctors should speak out proactively on all health issues, and that collective action of this type is a hallmark of professionalism. This lack of consensus needs to be debated. Recent developments such as clinical leadership have not revitalised physician advocacy. However, continued deterioration of the UK National Health Service has led some English medical colleges to take up open advocacy in its defence. It is to be seen whether medical colleges elsewhere follow suit, as and when their healthcare systems are similarly threatened.

AIMS: In this pilot study, the primary aim was to compare four potential methods for undertaking a national survey of unmet secondary healthcare need in New Zealand (one collecting data from GPs, and three from community surveys). The secondary aim was to obtain an estimate of the prevalence of unmet secondary healthcare need, to inform sample size calculations for a national survey. METHODS: An electronic system was set up for GPs in Christchurch (Pegasus PHO) and Auckland (Auckland PHO) to record cases of unmet need as encountered in clinics. For the community surveys, a questionnaire developed by the authors was administered to people from the same electoral wards as the GP clinics. Three modes of questionnaire administration were trialled: online, telephone and face-to-face interview. Random population sampling from the Maori and General Electoral Rolls was used to identify eligible survey participants until there were approximately 200 respondents for each method in each city. Data collection took place from November 2015 to February 2016. RESULTS: GP reports: Pegasus PHO: 8/78 eligible practices recorded 28 cases of unmet secondary healthcare need in 10 weeks. Auckland PHO: 3/26 practices participated and recorded no cases in three weeks. Surveys: 1,277 interviews were completed (online 428, telephone 447, face-to-face 402). For primary healthcare, 211/1,277 (16.5%) had missed a GP visit because of cost (online 25.0%, telephone 11.6%, face-to-face 12.9%). For secondary healthcare, 119/1,277 (9.3%) reported unmet healthcare need that had been identified by a health professional (online 11.2%; telephone 9.2%; face-to-face 7.5%). Of these, 75/119 (63.0%) required a consultation, and 47/119 (39.5%) required a procedure. Completed interview rates as a percentage of names on the Electoral Roll were low (online 8.8%, telephone 15.4%, face-to-face 13.9%), affected by changed addresses and lack of listed telephone numbers. The response rate for those with valid phone numbers was 47.6%, and for those with valid addresses was 31.5%. CONCLUSIONS: Using the Electoral Rolls to identify respondents is problematic. For a national survey, random population sampling by address, similar to the method employed for the New Zealand Health Survey, but giving respondents a choice between face-to-face and phone interviews, is proposed. Asking GPs to record data on unmet need for secondary care was not successful. Our pilot study suggests there is sufficient unmet secondary healthcare need in New Zealand to merit a national survey.

Successive New Zealand governments have claimed that the cost of funding the country's public healthcare services is excessive and unsustainable. We contest that these claims are based on a misrepresentation of healthcare spending. Using data from the New Zealand Treasury and the Organisation for Economic Cooperation and Development (OECD), we show how government spending as a whole is low compared with most other OECD countries and is falling as a proportion of GDP. New Zealand has a modest level of health spending overall, but government health spending is also falling as a proportion of GDP. Together, the data indicate the New Zealand Government can afford to spend more on healthcare. We identify compelling reasons why it should do so, including forecast growing health need, signs of increasing unmet need, and the fact that if health needs are not met the costs still have to be borne by the economy. The evidence further suggests it is economically and socially beneficial to meet health needs through a public health system. An honest appraisal and public debate is needed to determine more appropriate levels of healthcare spending.

Elective surgical repair was the general policy for the treatment of asymptomatic and minimally symptomatic inguinal hernias, based on reducing the risks of possible future bowel obstruction or visceral strangulation. Two randomised controlled trials in 2006 suggested that an alternative policy of "watchful waiting" was safe and appropriate. As a result, some health authorities in the UK withdrew funding for elective surgical repair for asymptomatic hernias in 2010. The long-term follow-up results of these two trials, however, showed high rates of surgery in the watchful waiting arms due to the development of symptoms. Two recent studies have called the watchful waiting policy into question on the basis of cost-effectiveness, quality of life and mortality data. The current article shows the results of an Official Information Act request of the New Zealand Ministry of Health and the 20 District Health Boards on their current policies for the management of such hernias. The results show a range of policies, with two District Health Boards employing watchful waiting, seven with policies or health pathways that can restrict or deny access to treatment, and all District Health Boards required to comply with Ministry of Health performance indicators. It is concluded that, at least with some District Health Boards, patients with asymptomatic and minimally symptomatic inguinal hernias are given a lower priority for surgical treatment than they might merit on clinical grounds. Further research is needed to formulate appropriate policy for the management of this common disorder, and should perhaps be extended to cover other similarly common conditions.

Major restructuring of the health sector has been undertaken in many countries, including New Zealand and England, yet objective assessment of the outcomes has rarely been recorded. In the absence of comprehensive objective data, the success or otherwise of health reforms has been inferred from narrowly-focussed data or anecdotal accounts. A recent example relates to a buoyant King's Fund report on the quest for integrated health and social care in Canterbury, New Zealand which prompted an equally supportive editorial article in the British Medical Journal (BMJ) suggesting it may contain lessons for England's National Health Service. At the same time, a report published in the New Zealand Medical Journal expressed concerns at the level of unmet healthcare needs in Canterbury. Neither report provided objective information about changes over time in the level of unmet healthcare needs in Canterbury. We propose that the performance of healthcare systems should be measured regularly, objectively and comprehensively through documentation of unmet healthcare needs as perceived by representative segments of the population at formal interview. Thereby the success or otherwise of organisational changes to a health system and its adequacy as demographics of the population evolve, even in the absence of major restructuring of the health sector, can be better documented.
